The principles of spatial data organization of distribution power networks in geographic information systems

Abstract

Spatial data in geographic information systems is organized in various ways. The first method is the principle of layer-by-layer organization of information (it is often called classical), the second is based on the object approach. The choice of models and methods of organizing data in geographic information systems is much more important than the choice of software package since it directly determines many of the functionality of geographic information systems. Some functions are either not implemented for certain ways of organizing data or they are provided by complex manipulations. The article discusses how to organize spatial data for presentation in geographic information systems. The analysis, comparison and justification of the use of an object-oriented method of representing spatial data for the display of rural distribution electric networks in geographic information systems are carried out. The structure of the “object tree” of the supporting scheme of the overhead line of 6-10 kV is proposed.
